Flares like the small hours, and the night before one is often short or broken. Nobody wants to write down how they slept. GoutMe takes the night from your wearable, your health app or, on Android, the phone alone, and compares it with your flare days. Short sleep and sleep apnea are one tap each for the nights no device saw.
Among 15,879 people with sleep apnoea and 63,296 without, 4.9% versus 2.6% went on to develop gout, a 42% higher risk after adjustment.
Blagojevic-Bucknall et al., Arthritis Rheumatol 2019Garmin, Oura, Polar and WHOOP connect directly; Apple Watch and most other devices come in through Apple Health on iPhone or Health Connect on Android. On Android the phone can estimate the night on its own: with usage access it reads the longest screen-off gap between 8 in the evening and noon as your sleep, ignoring gaps under two hours. iPhones do not share that, so on iOS sleep needs Apple Health or a wearable.
Each sleep signal is tested against your flares with the same statistics as everything else. What Strengthens You shows the other side: the sleep habits that turn up on your days with no flare.
Sleep apnea travels with gout more often than chance, so it has its own one-tap trigger for the nights you know were bad, and a wearable's SpO2 low early sign fills in some of the nights you did not notice. Whether it matters for your flares is a question the app answers from your own data, not from the leaflet.
Monitor and then Sleep: last night at the top with duration, when you fell asleep and when you woke, then efficiency, disturbances, score and the deep, REM and light stages, with the history underneath and your flares laid over it. Data lets you pick the source for each sleep metric.
A wearable, Apple Health or Health Connect for stages and a score. On Android the phone can give sleep timing alone with usage access. History graphs are part of Premium; the night itself is collected on the free app.
On Android, the timing, yes: with usage access it reads the longest screen-off gap between evening and noon as your sleep. Stages and a score need a wearable or a health app. On iPhone, sleep comes from Apple Health or a wearable.
Garmin, Oura, Polar, WHOOP, Apple Health on iPhone, Health Connect on Android, and the phone itself on Android.
Both. The night is stored as data, and the sleep triggers fire from it when a value crosses its line, so sleep is tested like any other factor.
